KeychainCheck 2 – thorough diagnostics and tools for your keychain
Completely rewritten, this uses lower-level access to keychains, and will offer sophisticated analysis to perform more thorough diagnosis of keychain problems, and provide tools to fix them. This new release has Help, text sizing, and many improvements, and is fully compatible with Catalina and Big Sur (apart from log feature).
